This chapter deals with fluid flow in the arc and the weld pool. It draws heavily on the work at UW‐Madison on computer simulation of weld‐pool convection, flow visualization, weld‐pool surface deformation and oscillation, ripple formation on the weld surface, and how these are affected by the surface‐active agent. The chapter also discusses the recent work on: (i) the metal−vapor effect on fluid flow in the arc, and (ii) fluid flow in the nugget in resistance spot welding (RSW).
